Like some private communities (5)
I believe the answer is:
gated
'like some private communities' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for gated that I've seen before include "kept in school" , "Barred from leaving" , "deprived of liberty for a while" , "Confined to school" , "Confined to college" .)
